I have a 92 Mercury 40 hp 4cyl. on my whaler. I just purchased the boat and took it out for a shakedown. The motor runs really well except for the random backfire and stall. I had changed the fuel thinking it may be bad with no change. I also changed all the spark plugs figuring I would...
Does anyone know if you can upgrade a steering system from a tiller (cable and pulley) system on a 1964-66 mercury 650 outboard? I have a 1958 Performer that has a really outdated steering system that isn't the safest in today's standards and would like to upgrade. Any help is appreciated.
Hey everyone,
I just finished changing the impeller on my 1968 mercury 650. Everything went together real well. I read that when I take the lower unit off it doesn't matter what gear its in as long as when I put it back together it is in reverse. I did that and now the prop runs in forward gear...
Does anyone know if the tins from a 454 mercruiser can be switched over to a 502 mercruiser. If so does that include the intake manifold and the distributor. I'm thinking of repowering my boat and was considering the 502's. Any advice would be appreciated.
After reading many of the posts I have built up the courage to start my own restoration. I believe it's a 71 or 72 Stinger I dont have any paperwork. It was given to me by my neighbor and well it needs a lot of work. I started by taking the two halves apart and all the interior out. It's...
I'm researching different types of long blocks for my Wellcraft. I have 1995 Gen V 7.4L in their now. I have been looking at US Engine at their website about 454 Magnum motors with 2" rectangular ports that have 55 more hp and torque in the 1500 to 4000 rpm range and use 20% less fuel than the...
Hello All,
I just got this cool Crestliner from a neighbor. I have done some research on the web and I think it's a 1971 or 72 Stinger. It has a Chrysler 45 that is missing the lower half. It has been left outside for probably close to 20 years. I took all the seats and the interior out and...
My oil pressure guage just started reading 0 the last time I took the boat out. I checked the oil and mototr and everything was running just fine. How can I test the guage and is their a sending unit to check. The motor is a 454 inboard Mercruiser.
I'm replacing the front crankshaft seal on my gen V mercruiser BB and I have read in a few other spots that maybe I should replace my harmonic balancer. I have looked at getting one and my question is are they just replaceable in an even swap? or are they balanced with the flywheel and have to...
I'm installing new manifolds on my 7.4 this weekend and was wondering if they have to be tourqued with a tourque wrench or not and if so does anyone know how many pounds?
I have a Gen V mercruiser that looks as though it's leaking from the front main seal. There is oil in the bilge directly underneath the pulleys. My question is this something I can replace without special tools once I get past the cover? Or could it possibly be from somewhere else?
I have a 95 Wellcraft Martinique with twin 454's. One of the motors has started dying after a few minutes of running. When I first start it, it runs great and then after a few minutes the tach and the volt guage begin jumping around the motor starts sputtering, backfiring and eventually dying...
